Differences in Signal Activation by LH and hCG are Mediated by the LH/CG Receptor's Extracellular Hinge Region.

Frontiers in endocrinology

Grzesik P, Kreuchwig A, Rutz C, Furkert J, Wiesner B, Schuelein R, Kleinau G, Gromoll J, Krause G.
PMID: 26441830

The human lutropin (hLH)/choriogonadotropin (hCG) receptor (LHCGR) can be activated by binding two slightly different gonadotropic glycoprotein hormones, choriogonadotropin (CG) - secreted by the placenta, and lutropin (LH) - produced by the pituitary. They induce different signaling profiles at...

Pharmacogenetics of FSH Action in the Male.

Frontiers in endocrinology

Male infertility is a major contributor to couple infertility, however in most cases it remains "idiopathic" and putative treatment regimens are lacking. This leads to a scenario in which intra-cytoplasmic spermatozoa injection (ICSI) is widely used in idiopathic male...

FSHB Genotype Identified as a Relevant Diagnostic Parameter Revealed by Cluster Analysis of Men With Idiopathic Infertility.

Frontiers in endocrinology

Krenz H, Sansone A, Kliesch S, Gromoll J, Schubert M.
PMID: 34992580
Front Endocrinol (Lausanne). 2021 Dec 21;12:780403. doi: 10.3389/fendo.2021.780403. eCollection 2021.

INTRODUCTION AND OBJECTIVES: About 30-75% of infertile men are diagnosed with idiopathic infertility, thereby lacking major causative factors to explain their impaired fertility status. In this study, we used a large cohort of idiopathic infertile men to determine whether...

Molecular Aging Markers in Patients with Klinefelter Syndrome.

Aging and disease

Pohl E, Muschal S, Kliesch S, Zitzmann M, Rohayem J, Gromoll J, Laurentino S.

Aging Dis. 2020 May 09;11(3):470-476. doi: 10.14336/AD.2019.0801. eCollection 2020 May.

Molecular aging markers provide the opportunity for biological age determination in humans and to study factors, such as genetic determinants, affecting the ageing process. In males with Klinefelter syndrome (KS, non-mosaic karyotype 47, XXY), which is the most common...

Healthy ageing and spermatogenesis.

Reproduction (Cambridge, England)

Pohl E, Gromoll J, Wistuba J, Laurentino S.
PMID: 33574214
Reproduction. 2021 Apr;161(4):R89-R101. doi: 10.1530/REP-20-0633.

Delayed family planning and increased parental age increase the risk for infertility and impaired offspring health. While the impact of ageing on oogenesis is well studied, this is less understood on spermatogenesis. Assessing ageing effects on the male germline...

BACKGROUND: In the United States, young men who have sex with men (YMSM) experience a disproportionate burden of HIV and sexually transmitted infections (STIs). Mobile health (mHealth) interventions, including those that incorporate elements of games ("gamification"), have the potential...

Silver-Russell syndrome (SRS) is a rare genetic condition primarily characterized by growth restriction and facial dysmorphisms. While hypomethylation of H19/IGF2:IG-DMR (imprinting control region 1 [IC1]) located at 11p15.5 and maternal uniparental disomy of chromosome 7 (upd[7]mat) are the most...
